Divided and 1950, Serial No. 171,663

The principal object provision of a machine for making end sheets for use in bookbinding, the machinev being adapted to utilize sheet forms of the type disclosed in United States Letters Patent No. 2,524,259, issued October 3, 1950, of which the present application is a division.

In certain types of binding for books, end sheets are placed in the front, and at the rear, of the book between the cover and the adjoining leaf or sheet. Actually, the so-called end sheet consists of two sheets or pages joined by a cloth hinge or analogous tape, and one of these sheets is glued to the inside of the book cover, while the remaining sheet of the pair becomes a ilysheet or the 'first page of the book (or the last sheet or page in the case of the end sheet at thev rear of the book) the purpose of these end sheets being to provide a iinished appearance to these parts of the book, and to aiord a connection between the cover members and the signatures of the book, it being understood that the ily leaf or sheet of each end sheet structure is glued or otherwise connected to the binding edge of the book signatures, by reason of which this sheet becomes in appearance and in effect one of thel leaves of the book.

In accordance with prior methods for making end sheets, two long sheets'of paper stock `were hingedly joined by a glued tape, Aand these joined sheets were cut across the middle so as to form two pairs of sheets joined by a tape, each pair of hingedly joined sheets thus becoming an end sheet assembly, one for the front, and the other for the rear of abook. Thusin bookbinding, an end sheet is in reality two sheets joined by some form of flexible hinge material, usually bookbinders cloth.

Machines are known in thebookbinding industry for attaching a tape to a pair of sheets which are to become end sheets, the joined sheets issuing from the machine in a connected series or chain which has to be severed manually between'v each set of sheets; and this arrangement is slow, subject to mistakes in making the cut, and re.

quires too close attendance and supervision; and since certain types of binding require two sets of end sheets, it is apparent that vast numbers of them must be used in the industry, and that any economy effected in time required for their manoi' this invention is theA 24 Claims. ('Cl. 11-1) ufacture, savings on costs by cuttingdown the.

number of rejects, or in supervisory or manufacturing attendance, can be of considerable sig'- niiicance in the cost of a run 'or an edition.

In accordance with the present inventiQnz therek Inc., Chicago, Ill., acorpora- Serial No.

No. 2,524,259, dated October this application July 1,

is provided a machine for attaching a tape to a form, such as shown in the aforesaid Patent No. 2,524,259, and then cutting the form so as to produce not two, but four sets of end sheets.

The invention further provides apparatus for the practice of part of the method of said patent in the particular of attaching the tape to the stock form and severing the taped form :to pro# vide the aforesaid four sets of end sheets. Y It is a further and more detailed object of the invention to provide a machine for accurately' feeding a prepared end sheet form to a cutting means, and for applying a tape hinge to said forni during its travel toward said cutting means, and for severing the forms accurately to produce four 'complete and disjoined sets of end sheets.

Additional detailed objects are: the provision in a machine of the type characterized above of means for traveling an end sheet form over a predetermined path or bed; means for registering the form at the start of its travel; means for appli/ing and gluing a hinge tape to a certain :part of the form before it reaches the end of its travel means for severing the hinge tapes between suc cessive forms at a certain point along the path of travel; means for severing the hinged form so as Vto provide a plurality of complete end sheet assemblies;` means rendering the several cutting means mentioned above adjustable to operateon forms of different size; means for rendering thev above-mentioned traveling means adjustable to means shiftable laterally of the direction of travel;

relative to said rollers; and a unitary adjusting control for simultaneously guide means.

Other objects and aspects of novelty and utilityA of the invention relate to the details of construe-f tion and operation of the apparatus described, hereinafter in view of the accompanying drawings in which:

Figs. 2li,Y 25, 26,V 27, V28, 28A, and 29 illustrate in perspective the steps for preparing end sheet forms, andapplying the hingeY tapes: thereto,

while Y Y Fig. shows. in perspective a finished end sheet assembly.

In accordance with the method of Patent' No. 2,524,259 as illustratedin Figs. v24 through 30, an end sheet form is preparedby manually or other- Wise` making folds 4S and d! in a piece, of endsheet stock, so that confronting edge. portions, 40A and MA lie. in a median portion of the sheet, leaving an exposed portion t2 extending longitudinally of theform for purposes to be described.

The. prepared form ofFig. 2i has applied to the said median edge' and the exposed portions a.

hinge cloth or tape d3, the underside of which, is.

glued or otherwise adhered to a substantial area of the paper adjoining edges 118A and lllA, and also to the entirety of the exposed portion 42, resulting in the form, with hinge applied, shown in 25.

Next, the hinged form is subjected to, aslitting process by means of which the form is divided into two halves along the longitudinal slit 44 down the center of the hinge member, this slit being made preferably by a cutting wheel W. lv'hereA the forms are used in conjunction with Y forming apparatussuch as described hereinafter,

a, series of the forms are connected by a continuous tapx-ifiA,A as. in Fig. 29, so that in the next operation and cutting of the divided form, Fig.

l 27, as: by knife means K, there is `an added cutting operation by knife means K to sever the series to the extent of one form at the same time as that form is itself cut, usually into two equal ,subsections or subcuts, resulting in the iinal production of four end sheet assemblies as shown in Fig. 2,8. I

In the. usual bookbinding practice, one of, these. end sheet. assemblies. would be` placed, on top ci a,Y gathering of book signatures, while another such assembly would be placed at the bottomoi said gathering, making up a book form, the, edge. portions of which would then be trimmed by power cutters, with the. result, amongothers, that the fold portions til and lll of the several. endv sheet assemblies would be cut, destroying the. fold connection, by reason of ywhich the two1 sheets comprising each end sheet assembly can be opened, like the other pages of the book, inY the. manner illustrated in Fig. 30..

At this stage of the bind-ing operation, thebook. covers, (not show-n)` can beapplied,A and if the end sheet. shown in Fig. 30 is the one. at the irontr of a boolnthen. the upper wing l5 would be glued to the inside ofv the front cover board, while the hinge portion alongA the binding edge indicated. at 4h would b e glued or seeuredto the bindingl ofv the leaves of the bookl signatures,I so that` the. secondor inner wing lll of this same assembly Wouldlturn, as though it were one of the. leaves of the book; and the same would betrue of the, assembly at the. rear ofthe book but in reverse.. that is, Wing il would be glued to the inside of'. the rear cover, while wing A5 would bea fly sheet.

DESCREPTION Mechanism for carrying outvcertain steps Aofi the end-sheet manufacturing process is shown in a general sidey view in Fig. l, wherein a frame 5B provides a traveling or feeding bed indicated generally at 5l and having its infeed end 52 at the righthand side of the sheet, and its discharge end' at the left thereof, including a collectingv stacker means 53 to receive the sets of end sheets" discharged. at each feeding operation of the machine.

Prepared sheet formsl such as heretofore described, are fed into the machine at the infeed` side 5 2, and after being registered are traveled over the bed 5I relative to a tape or hinge applying means, including an overhead tape supply reel 54', guide roller meansv ii'directingone side ofthe tape web 55 over a large gluing roller 5T, which picks up glue or adhesive from a small' tank 58 on the overhead structure 59, the glued tape being, fed reversely over roller means 5!! on said structure in such manner that the leading wehpor'tion 59A. thereof is again reversed to pre-- sent the glued side downwardly under roller means (it, which feeds. the tape in timed relation to. the advance or travel of the` forms. therebeneath, With the result that tne tape is continuously applied'to a succession of forms in4 the manner illustrated in Fig. 29.

As the taped sheet formscontinue their travel over-the bed by a series of lintermittent advancing steps, the slitting andcutting operations, heretofore described, are performed, by means includingy (Fig. 2) a slitter wheel`62, and tworeciprocating cutters |60 and. |6| adjacent the discharge side of the machine, with the result that for each operating". cycle of the machine, a s et of four end sheet assemblies,.su`ch as-'shown in Fig. 28, will be dischargedinto the stacker meansv 53.

DETAILEDDEscRrPfrioN. Infeed bed and adjustable register The machine is contrived to "accommodate forms of different size, and r4to this end there is provided a feeding `or traveling'bed which is adjustable as a width, andfwhich also includes certai-n adjustable sections and cooperating instrumentalities. t v

Considering the infeed end ofthe machine,

shown to enlarged scale in Fig. 14, there is aA lon` gitudinally shiftable register section consisting of three wide bed plates 19 having support on cross bearers 1|, which in turn are carried on parallel, longitudinally slidable sideplates 12 supported on'the frame structure asy illustrated in the sectional view of Figs. 18, 19, there being intervening narrow bed bars 13running the near length of the bed, which are fixed, between the innermost wide bar and the two adjoining bars 10.

As seen in Fig. 18, the slidable side plates 12 each have a rack bar 'Mattached thereto, with which mesh pinions 15 fast on an adjusting cross shaft 16 journaled in the frame and provided with adjusting hand wheel 11. By turning the hand Wheel oppositely, the side plates, and hence the bed Ibars 10 may be shifted longitudinally of the machine to set the registering fingers 18 (Figs. 14 andA 17) in accordance with the length of end sheet form to be fed into themachine, a' scale 19 calibrated in inches moving with the section relative to an index mark (not seen) to facilitate this adjustment, so that the forms will be started accurately relative to the infeed roller means and tape-applying means for precise movement of the forms relative to the cut-off knivesto be described.

The aforesaid wide bed plates 10 terminate at an infeed presser roller 80 on cross shaft 8| carried at the ends of a pair of lever arms 82 (Figs.

14, 16, 17) rockably attached as at 83 to saidV shiftable side plates, such that said roller can be rocked toward and away from a driven feed roller 84 on cross shaft 85 also journaled inthe shiftable side plate section; vand in addition to the centrally located feed roller are anking companion feed rollers 86 also fast on shaft 85, the latter being rotated intermittently through a pinion 81 (Figs. 14 and 17) meshingwith pinion 88 slidably keyed as at 89 on a continuous roller drive shaft 90 on the outside of the frame. Thus,

when the slidable register section is moved back and forth, pinions 81 and 88 move with it, the long drive shaft 90 being intermittently ret-ated by means to be described. g

The arrangement is such that the registering fingers 18 reciprocate vertically to be projected and then withdrawn from the path of the incoming sheet forms, serving to stopy or register the starting position of such forms when raised, and

in order that the forms may be fully' positioned' against these fingers, the presser rollei-"B is con 61. trived'to be raised also when theregister fingers are raised, this construction beingbest understood by reference to Figs. 16 and 17, wherein it appears that the ngers 18 are attachedltc rocker arms 9| pivoting at 92 on the movable section structure, there being links 93 connecting from said rocker arms to cranks 94, as at 95, said cranks being fast on rocker shaft 96, rocked intermittenly through a crank connection 91 actuated by a long reciprocating -drive rodV |58,` from `the drive mechanism near the discharge end of the machine, to be described.

Presser rollerV 00 is raised and lowered by means of another crank 99 near each end of shaft 96, and corresponding links |00 connecting as at |0| with respective roller rocker arms 82.

i the longitudinal shafte in themain frame structure, the

The registering lingers 18 are of spring metal with their upper portions projecting through guide slots in shortl lbed bar sections |02 so that they may iiex in reciprocationby the arcuately moving cranks. l 'Y A further feature of adjustment of the feeding bed structure includes a pair of angle irons |04 extending longitudinally of the machine from the infeed end almost to the first cut-off knife |60, as in Fig. 2,' the upstanding edge portions of these angles providing marginal guidesfor the paper forms; as will be apparent from Fig. 17; and these angles are arranged to rest on cross bearers, including bearers 1| along the extent of their` length, and are further respectivelyl attached to blocks threadably engaging right andlefthand threaded portions |06 (Figs. 6l and 14) of a pair of longitudinally spaced apart crossshafts each having a, bevel pinion |01 meshing with al companion pinion |08 on a longitudinally extending adjusting shaft on the outside of the frame, the said cross shaft near the discharge end ofthe machine, asin Fig. 6, having a knob I6 by which the right and lefthand threaded cross shafts may be simultaneously turned,1thro'ugh cooperation of |09, to cause the pair of angles |04 to shift laterally, that is towardv or` away fromy each other, to accommodate the-de'- sired Width of end sheet form. l i Sheet presser fingers i I2, such as shown toenlarged scale in Fig. 22, are carried on blocks I3 slidably fitted on the upstanding edge portions of the angle guides |04, as in Figs. 2 and Vv1 4, lto hold down the formsin movement along the bed.

Intermittent roller ,feed and kdriee-'mechanzism A plurality of intermediate feed rollersV |20, of the .general construction shown inV Fig. lul, are

preferably of metal with knurling orse'rratio-n's,v and'being carried on cross shafts tion, the pawls |26 will slip over the teeth of gear |28 and the feed roller |20 will not'rotate. 'K `Countersh-aft |21 is rotatedin opposite direc-4' tions alternately through 'a pinion |30 meshing anodine.

7 (Fig. l1) with a reciprocating rack |73 t, sliding in yoke |32 (Fig. l) under urgence of rod connection |33 with slide crank |34 on countershaft which (Fig. 1) is driven. through gears |36, |.3.1, 38, |39 and main power `shaft |40, driven bymotor |4| and belt pulley |42.

Cooperating with the several feed rollers |2|i are presser rollers |20A (Figs. 1 and 2) on rocker arms IZBB held down by coil springs |260 to flimits determined by setting of tappets |2|1D (Fig. 1)-, these presser rollers being driven from pinions |20E meshing with pinions |2||F` on the main roller shafts.. as. in the case of the master roller of Fig. 11.

slitting, cut-017 and register mechanism The slitting means includes the beveled cutting wheel `(i2 of Fig. 2 on cross shaft |50, which, as seen better in Figs. 6 and 1, is driven through pinion |5| meshing with pinion |52 (Fig. '1) on cross shaft |53, which terminates at the side of the machine in a, hand adjusting wheel |54, as in Fig. 6; and as in the latter view, shaft |53 is driven through sprocket gear |55, chain |56. sprocket gear |51 (Fig. '7) on countershaft |58. Sprocket chain |55 is tensioned by a rocker idling sprocket |59, Fig. 7.

Since gears |31, |38 on shaft |58 drive with the main power shaft |40, Fig. 7, it isapparent that turning of hand wheel |54 imparts operating motion to the entire machine, as when the motor |4| is turned off, by which means the working parts may be slowly moved into desired positions, relatively, to facilitate adjustments in the width of the feed bed, the relative position of the adjustable. registering unit at the infeed end of the machine, starting of the hinge tape feed, etc.

The slitting operation is eiectedby wheel 52, appropriately beveled to give it a cutting edge, and a companion wheel 52A on said cross shaft |53, Figs. 'l and 8, the end sheet forms passing between these two slitting wheels to effectuate the hinge cut 44 by wheel kmeans W, Lsuggested in Fig. 26.

In order to hold down the now two sections. of the end sheet form after slitting, there is provided a special hold-down or presser roller construction of the type shown in Figs. 6` and 11., and consisting of a central roller |28H having two axially spaced circumferential rings IZIIJ, and flanked by v'additional roller elements |20K, the rings |20J engaging the hinge portions close to the slitting line, and the additional rollers IZUK assisting in keeping the course of the severed halves straight.

The aforesaid presser roller means |20H, |20K; cooperates with feed roller means |29, driven as explained in connection with the construction of Fig. 11.

After'passing through the slitting means, the severed portions of the end sheet forms advance the full length thereof between open shearing and cut-off means including (Figs. 6 and '1)' two vertically reciprocable knives |60 and |6| having the-general construction shown in. Fig. 10, which depicts the second, and last, of the two knives, |6|, the latter differing mainly from the first knife |60 in that the latter is not adjustably movable, while the former is, and there are other differences to be explained hereinafter.

For convenience, the knife structure is de scribed generally in view of Fig. 10, wherein it is seen that the knife unit consists of a lower. stationary blade-holding bar |6|A secured in castings. IGIB on opposite sides of the machine (Fig. 7 particularly) with a lower blade |61 C'l secured to said bar.

The upper portions of said castings |6|B are formed to provide vertical slots or yoke-s, as at |6|D (or |60D), Figs. 7 land l0, in which a mov-r able knife bar vMilli! (or |E) nts for vertical.l reciprocation under urgence of crank arms |6|F (or |60F) pivoted thereto, as 4at |6|G (or ISUG), yand normally pulled downwardly by springs Hill-l,A which are largely concealed from view, but which are attached to the lower ends of rods |6|X partly seen in Fig. '1, said rods in turn pro.- jecting downwardly from the movable knife bar |6|E and having said springs attached thereto, said springs in turn being anchored to pins carried by certain yoke arms |12, Fig. 10, to be described.

A difference in the arrangement of the twoy knife units resides in the connection of springs [Gill-I, Fig. 8, for the first knife bar IEDE to the lower ends, respectively, of the two cam rods ISEF- thereof, these springs being anchored to themain frame.

Returning to the knife unit construction shown. in Fig. l0, there is a knife blade |6|J secured to the reciprocating bar |6|E and shearing with the .stationary lower .blade |6|C.

Reciprocation of the movable blade carriers is effected in timed relation to other operations in the machine by means of cam riders |.6IK rolling on especially developed cams |6|L slidably keyed, as at |6|M, on short side shafts |60N, the latter shaft on the lefthand side of the machine being driven through bevel gears liil, shaft IBBQ, and bevel gears IBJR, with the shaft HillNV on the righthand side of the machine, asin Fig. 9.. Shaft Q is driven with the main power takeoff means shown in Fig. 7 in particulars explained hereinafter.

The cam drive for the nrst knife unit |60 illus* trated in Fig. 8 differsvfrom that just described for the second unit in that the cams iiil.. are fixed on shafts SSGN and lN, and do not slide there-v on as do the cams IBIL, and for this reason thesprings |'60H may be anchored to the mainframe, since the corresponding cutoff or knife unit does not move, as does the second knife unit |6|.

The rst or inner knife unit |60v is properly a cut-off means in that it severs the leading set of endsheets from the next succeeding form, while the second or terminal knife unit |S| is a multiplying knife since it divides the slit forms into a plurality of endsheet assemblies, cooperably with the slitting functions of slitting wheels G2, 62A;

` and a notable difference between the second or terminal knife means |61 and the inner or cutoff knife means |63, resides in thefact that unit |6| is adjustably movable longitudinally of the machine.

In Fig. 10 it will be observed that the Casting members |zi|B are carried on a table or plate |18 keyed, as at |1|, into the machine framework to slide longitudinally; and depending from this plate are yoke arms |12 secured to the table so as to move therewith; the yoke ends of these arms fit into annular grooves |14 (Fig. 7) formed in the movable cams |6|L such that when the table or plate |10 shifts, cams IEIL shift with it.

Longitudinal adjustment of the movable knife unit is effected through means shown in Figs. 'I' and l() and including a threaded shaft |15 turned through bevel gears |11 when the hand wheel |18 0f Fig. 9 is adjusted, thereby moving plate llt'- through the threaded traveler block |16 on the clined plate rod 98, as at bottom thereof. Such adjustment of the terminal knife unit determines the relative length of the resides in the fact that the movable unit |6| carries with it its own assembly of feeding rollers, including a pair of lower driving rollers |80 (Figs.

6 and '7) driven through bevel gears |8| (Fig. 6)

meshing with bevel gears |82 slidably keyed on the long side shaft 90, which is rotated unidirecu tionally and intermittently in the' manner heretofore described. Y

There is one of the driving feed rollers |80 on each side of the movable knife means |||,y and each said vroller has a companion upper roller means |85, Figs. 6 and,-7, similar to the roller 'means |2011, |20J, andil each driven through pinions |86 meshing with companion pinions (not visible) on the corresponding shafts of rollers |80, as in the case of the construction of Fig;

11. Thus, the movable or adjustable multiplying knife unit includes anking feed roller means movable therewith. As seen in Fig. 6, there is provided a scale |81, calibrated preferably in inches, moving relatively to index arrow |88, Fig. 8, to facilitate setting of the movable knife unit.

The operative timing of the feeding or advancing operation of roller means |80, |85 is calculated to occur when the knives |60, |6| are open, such that the four completevendsheet assemblies resulting from the cutting or shearing operation thereof will be simultaneously discharged from the machine into the stacking means generally indicated at 53, and including, as best seenin Figs. 1 and 6, a downwardly inclined apron 53A having an upstanding stop plate 53B at its lower end with a centrally located, upstan-ding partition plate 53C flanked by upstanding wings 53D mounted on the apron for lateral movement by attaching bolts Working in slots 53E therein; and the wings have laterally offset sheet guide protrusions 53F thereon. Situated above the apron 53A is a downwardly in- 53G, Fig. 7, having its upper edge situated close |80, |85 on that side of the terminal knife, so that the severed sheets are initially guided for lodgement against the stop plate 53B in stacks on'v opposite sides of the partition plate 53C.

As an important partV of the operative timing of the machine, the

register fingers 18 of'Fig. 16

' must rise into form-stopping position at a certain instant relative to the opening of initial feed roller means 80, 86, and otheroperations of the machine, and to this end, the reciprocating rod 98 which actuates the lever mechanism for raising and lowering the register fingers, as heretofore described, is driven from the same cross shaft |60Q employed to actuate the knife units,'the

means for accomplishing this including a 'cam |90, Figs. '1 and 9, on said shaft, upon which rides roller 9| on pitman link |92 pivoted on said drive |93, Fig. 9 there being a pair of flanking springs |94 attached as at |95 to the rod 98 as at |91 on a cross bearer or tierod in the frame, said spring means serving to urge rod 98 toward the left and maintain the cam roller on the cam.

Shaft |60Qiis driven constantly from power.`

to the discharge side of roller meansl and anchored on upright rods |96 clampedv which guidey springs the '10 gear' |36'through intermediate gearV |99 and gear 200 on said shaft liiQ;` and intermittent reciprocation of the two knife units |60, |6|, as well as the register actuating rod 93,v occurs in timed relation as the respective cam means |60L and |6|L, and |90 are constantly rotated, whereas the :intermittent operation of the several feedy roller means is effected through the unidirectional clutch means |3| heretofore |24 and reciprocating rack means described, the slitting wheel means Y 62, 62A rotating constantly.

The same intermittent operation of the several feed rollers above-mentioned characterizes the tape feeding movements of the special tape feed roller means 6| and the cooperating feed roller Vmeans |20X, which is driven from the common cr longside shaft 90 in the same manner as the master roller means |20 of Fig. 11; and in addition, positive intermittent drive is effected on the gluing wheel 51,V Fig. 1, by means of sprocket chain 51A driven from a sprocket gear (not seen) on the feed roller shaft of roller means |20Y, Fig. 1.

The hinge tape portion 56A passes around an idler roller 56B, Fig. 14, before passing beneath roller means 6| and 20X, and there are provided a pair of guide leaf springs 56C on arm 56D carried on fingers 56E which are, in turn, carried on a rod 56F in rockerarms |20B, over tape feeds between the feeding rollers.

In connection with the gluing roller 51 shown in Fig. 3, attention is called to the top plan view of Fig. 4 thereof, and to annular grooves 51A spaced apart axially therein for the purpose of laying the glue in three separate tracks on the tape as indicated at 56X, 56Y, and 562, Fig. 5, by reason of which the hinge tape is glued centrally Ato the endsheet form portion indicated at 42 in Fig. 24, such that when this portion is slit along VThe machine is rst i Fig.l 6, to shift the angle guides the line 44 as in Fig. 26, there will be the glued 'attachment indicated at 46 in Fig. 30 for both slit halves of the form, the two outer glue stripsSGX and 56Z becoming attached to the top form leaves Summary of operation prepared form of Fig. 24

Next, the hand-wheel |18 (Figs. 6 and 9) is turned to shift the movable knife units |68, |6| lengthwise or the machine so that the cut-on and multiplying cuts made by these units, respectively, will likewise be in accordance with the length of said form, the shifting of said units being eiected through pinion means |11 and the screw shaft |15 of Fig. 9 moving the threaded portion |16 to shift the casting which carries the reciprocating knives IEDE, IEEE, as in Fig. '7.

With the foregoing principal adjustments, and a correspondingly appropriate adjustment of the kstacker Wings 53D (Fig. 6), the machine is in and an operator then feeds the prepared forms shown in Fig. 24 belneath 'the infeed roller 89 (Fig. l) which is periodically raised, so that the leading or inward edge of the form stops against the raised registering iinger i8 (Fig. 15). r

The prepared form consists of a paper sheet having opposite side edges folded .inwardly tosaid edges are oppositely disposed in parallelism but spaced apart to leave `a median exposed portion 4.2 as in Fig. 24, this exposed portion being fed into the machine up- -permost Upon the next intermediate feeding action Vof the machine the infeed Aroller Sil will close with finger `form may advance bemeans and the tape web 55A which has its underside coated with an adhesive or glue in three `parallel tracks 56X, 5|iY, .and56Z, as shown in Fig. 5, the central adhesive track v565? being superimposed upon` the aforesaid median exposed portion 42 of the form and one of each of the two remaining tracks being superimposed upon one of the parallel edges 40A or 41A of the form and an adjoining portion of said median exposed portion, the tape being pressed against the advancing for-m beneath rollwill descend `so that the I er means 6 l.

The form with tape applied as aforesaid is now advanced step-by-step through the action of intermediate feed rollers |20 along the .feeding Vbed toward the slitting wheels 62, -6/2A (Fig. 6) by reason of which the taped form is now slit lengthwise, as along the line-44 of Fig.. 26, to divide said form into two halves or sections at the middle of the tape, it being observed that said tape is continuously fed as from the reel 54 (Fig. 1)., so that i the advancing forms are connected in series.

After slitting, the two sections continue their adunits |66, |61, and the reciprocating knife members MOE-IEM, -|6|E-'|B|J, with the forms sc positioned relative thereto that upon the timed descent 'of the reciprocating members ISUE, ISEE, the leading form (which is now slit into two halves as aforesaid) will be cut oi at its tape juncture with the immediate succeeding form, and at the same time the two halves of the leading form Yportions 'will be cut in half, as in Fig. 27'to .provide the multiple end-sheet forms shown in Fig. 28, and upon `the next advancing operation of the machine said multiple forms will be discharged by action of the roller means |85 (Fig. 7) into the stacker -means 53 (Figs. 1 and 6, also).

iin the foregoing operation all of the vfeed Vrollers operate intermittently in synchronism, including the special infeed roller means iiD- 86,

-the intermediate .roller means generally indicated by references |20, inclusive of the `special 12 tape-applying roller means S'I-JZBX as well as the movable discharge roller units M30- |85 associated with the cut-ofi and multiplier knife means.
